LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 673,836, dated May 7,1901.

Application filed October 1900. Serial No. 31,998- kNo model.)

To all whom, it may concern.-

Be it known that we, SERVETUS G. GRAY and WILLIAM J AMES 00X, citizensof the United States, residing at Nashville, in the county of Davidsonand State of Tennessee, have invented certain new and usefulImprovements in Lubricators; and we do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The invention relates to lubricators, and more particularly to thatclass of lubricators designed for lubricating traction-rails at curvesto permit of the cars more easily passing around the same.

One object of the invention is to improve the construction showninPatent No. 657,482, granted to us September 4, 1900, by making provisionfor lubricating the rails with oil instead of a semiplastic lubricant.

A further object is to provide means for shielding thedistributing-brush when not in use to prevent lodgment and accumulationthereon of all foreign matter, such as dust and the like.

A still further object is to provide means for scraping the wheel of acar against which the brush acts, so that any substance which tends tolodge upon said wheel will not be brought in contact with the brush, andthereby clog or damage the same.

With these and other objects in view the invention consists in certainfeatures of construction and combination of parts, which will behereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a side view of the frontportion of a streetcar, illustrating the application of our invention.Fig. 2 is a bottom plan view. Fig. 3 is an enlarged detail plan view ofthe lubricator removed, and Fig. 4 is a vertical longitudinal sectionalview.

Referring to the drawings, 1 denotes the platform of a street-car, and 2the front wheels thereof.

3 denotes the oil-supply tank, provided wheels and having a filling-tube5, extending up through the floorof the car and closed by a cap 6.

7 denotes the lubricator, which preferably consists of a tubular casing8, in which is mounted to slide a discharge-tube 9, having an aperture10, which is adapted to be brought into alinement with a nipple 11, towhich a pipe or hose 12 is connected and leads to the oil-supply tank. Acoil-spring 13 is connected at one end to the tube and at the other endto a cap 14: at the rear end of the casing and serves to hold the tubein the position shown in Fig. 4that is, with its aperture out ofalinement with the nippleso as to cut off the supply of oil from saidtube. The outer end of the tube is provided with a stuffingbox 15 toprevent the escape of oil between the outer surface of the tube and theinner surface or wall of the casing. Secured to the outer end of thetube by a clamp 16, similar in construction to the clamp used forattaching the hose to the nipple, is a distributingbrush 17, which isadapted to engage the inner side of the flange of the wheel, and therebydischarge oil upon said flange, so that it may be distributed upon theguard-rails at the curves of the track. The casing may be secured to thebottom of the car in any suit.-

able manner, and is shown in the present instance as being provided withan outer and inner set of longitudinally-perforated ears 18 and 19 topermit them to be attached to depending brackets from the bottom of thecar and be adjusted with proper relation to the wheels.

Any suitable means may be employed for alining the aperture of thedischarge-tube with the nipple of the casing, and in the presentinstance we have shown a lever 20, piv-. oted to one of the ears andconnected to the forward end of the discharge-tube by a piv' oted link21. A push-rod 22 works through a hole in the platform of the car and ispivoted to a crank-wheel 22. Alink 23 connects the crank-wheel with thelever in a manner similar to that shown in our patent hereiubeforereferred to. By compressing this push-rod the discharge-tube will beforced outward against the tension of its spring and the brush bebrought into contact with the inner side of the wheel-fiange. To limitthe outward movement of the discharge-tube, any suitable means may beprovided; but that shown in the present instance consists of a stopscrew or stud 24, secured to the casing and projecting into alongitudinal slot 25, formed in the discharge-tube.

As the wheels are likely to gather up the dust, mud, grease, and otherforeign matter upon the track and as it is desirable to prevent theseforeign substances from coming in contact with the brush when the latteris applied to the wheel, we provide a scraper 26, which is locatedimmediately at the rear of the front axle on the wheels and is inengagement with the inner face of the wheel-flange, so as to remove allforeign substances therefrom, and thus present the clean surface of thewheel to the brush when it is brought in contact with the wheel, thuspreventing the clogging of the brush. This scraper is preferably made ofspringy material.

To shield the brush from flying dust and the like, we provide a hood orshield 27, which is preferably made of sheet metal and is semicircularin cross-section. The inner end of the shield is provided withlongitudinal notches or slots which slip over the outer ears of thecasing and is held in place by set-screws 28, which engage the casing atopposite points below its axis.

The Wear of the brush may be compensated for by adjusting the inner endof the link 21 in the apertures of the curved head of the lever or byadjusting the link 23 in the apertures of the arm of the lever.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, operation, and advantages ofour invention will be readily understood without requiring an extendedexplanation.

The device is exceedingly useful for the purpose for which it isdesigned and may be this invention.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. The combination with an oil -su pply tank, of a lubricator secured tothe bottom of a car and comprising a casing and a discharge-tube havinga sliding movement within said casing and provided with an apertureadapted to aline with a nipple carried by said casing, a pipe connectingthe oil-supply tank with the nipple, and means for aliuing the apertureof the discharge-tube with the nipple, substantially as set forth.

2. The combination with the wheels of a car, of a scraper located andarranged in a position to scrape the inner side of the Wheelflange, anda luhricator arranged to discharge a lubricant upon the inner side ofthe wheel- 'flange at a point in advance of the scraper, substantiallyas set forth.

3. In a lubricator, the combination with a casing having aninlet-opening, ofa dischargetube mounted to slide in the casing andprovided with an opening adapted to be brought into register with anopening in the casing, means for moving the oil-supply tube, and ashield or dust guard attached to the casing to cover the outer end ofthe supply-tube, substantially as set forth.

In testimony whereof we have hereunto set our hands in presence of twosubscribing Witnesses.
